My Neutron Vector has a slight dome and comes to a point in the center. I would not call it overstable at all, but it always fades on a clean throw. It flies very similar to my Neutron Axis, but on lower lines. I.E. if I give my Axis more height it will fly similarly to the Vector where as normally it has a tendency to finish straight.
